FRESH-AIR-SU'PPLY DEVICE.

Specification of Letters Patent.-

Patented Oct. 26, 1909.

Application filed August 3, 1906. Serial No. 329,092.

To all whom it may concern:

Be it known that I, FRANK S. LIPPITT, a citizen of the United States,resident of Cleveland, county of Guyahoga and State of Ohio, haveinvented a new and useful Improvement in Fresh-Air-Supply Devices, ofwhich the following is a specification, the principle of the inventionbeing herein explained and the best mode in which I have contemplatedapplying that principle, so as to distinguish it from other inventions.

My invention relates to means for supply ing fresh air to patients inhospitals and sick rooms. As will be obvious it is equally well adapted,when desired, for use in the sleeping apartments of well persons.

The object of my invention is to provide means of the characterindicated that will be neat in appearance and convenient in their mannerof attachment and use, and that, furthermore, willinsure not only accessof the outside air to the person using the same but a continuouscirculation of such air by or over him if required.

Said invention consists of means hereinafter fully described andspecifically set forth in the claims.

The annexed drawing and the following description set forth in detailcertain means embodying the invention, such disclosed means constitutingbut one of various me chanical forms in which the principle of theinvention may be used.

In said annexed drawing: Figure 1 represents a front elevation of mydevice, showing the same attached to a window of a sleeping room andproperly positioned for use over a bed; Fig. 2 is a plan view of suchdevice; and Fig. 3 is a side elevation as viewed from the left in Fig.1.

As will appear from an inspection of such figures my invention, asembodied in the form there shown, comprises first of all a canopy orinclosure A that hangs loosely over the head end of the bed, beingconveniently supported at D against the frame E of such bed. An approvedconstruction of this canopy is to make a substantially rectangular frameover which cloth of a suitable quality is stretched so as to entirelyin-- close the sides and top of such frame except as hereinafterspecified Since'the bottom of the frame should rest but loosely on upperportion of the bed, in order not to discommode the patient, the clothcovering of the frame should be provided with a ruffle or apron as shownto prevent unnecessary escape of outside air into the room.

This cloth covering is detachably secured to the frame, which latter forthe sake of lightness is made of wire or similar material, and may hencebe removed whenever necessary for laundering. To permit the patient tolook without the canopy it is desirable to provide a window K,preferably of flexible material, in the front of canopy, suchwindowbeing merely laced or otherwise detachably secured to the canopy side inorder that it may be readily removed when the canopy is being laundered.To provide for the free access of pure outside air to the patient, whichis the desideratum here sought to be accomplished, the canopy A, as thusdescribed, is connected by a suitable duct or passage, or a plurality ofducts or passages with the exterior, as an open window, F. In the formof the device illustrated two such passages are shown one B leading fromthelower part of the window and connected with a side of the canopy, inwhich a suit able opening is of course made, the other C leading fromthe upper portion of the window and connected with the top of the canopywhich may be of pyramidal or conical form as appears in the figures ofthe drawing. These passages are preferably constructed, as is canopy A,of cloth stretched over a light frame-work which may or may not becollapsible just as desired depending upon whether the device is a moreor less permanent fixture. As shown, the upper duct is of smallerdiameter than the lower one and is connected with a suitable opening ina board I inserted above the upper sash of the window. The outer end orthe lower passage is supported on two transverse rods B. Fig. 3, anyunoccupied portion of the window frame being closed by a curtain S.

Provision for vertical adjustment of the canopyA over the bed andpatient may be easily effected by attaching cords N to the canopy andlower passage at points P P, respectively, and passing these cordsthrough pulleys L hung at a suitable height above the bed. By means ofthese the canopy can be conveniently raised when the patient so desiresor to permit the attendant to arrange the bed.

The operation of my improved device is quite simple and should beevident from the foregoing description of its construction.-

' I is set up and maintained by theslightheating effect of the body of.patient which warms the air sufliciently to cause thesame to seek toascend. I would not be understood, however, to imply that a second ductlike 0, is essential to securing such circula tion, for I have foundthatwhere-the lower duct as B is of large enough cross-section it willaccommodate both an inflowing and outflowing current of air. In otherwords, the provision of separate openings at different levelscommunicating with the exterior of the apartment taken in conjunctionwith the heating effect of the body of the patient above referred towould suffice for establish ing and maintaining the desired circulation.

By'the use of my device, it is hence seen, all the advantages ofsleeping out of doors, lately so much emphasized'by'medical ex perts andothers, are secured by the fresh air devotee while enjoying all thecomforts and conveniences of a modern bed room,

and without encountering'the rigors attend ant upon an unexpectedrainfall or snow. The advantages of the use of a device of this kind inhospitals and sanitaria where fresh air if procurable is frequently thebest medicine, not only for the convalescent but also for the patientwhile still critically ill, are inestimable. It should be noted in thisconnection that the circulation of air induced in the mannerpreviouslysetup is gentle and partakesin no Wise of the characterof a draft suchas is apt to prove'disas trous to even the hardy person who ventures tosleep by an open Window. The conven ience with which my device, in theapproved form here shown, can be set up and handled will further commendit to the user.

lI-Iaving thus'described my invention in detail, that whichI'particulary point out and distinctly claim, is

l. A fresh'air-supply device for a sleeping apartment, comprising aninclosure adapted to'be supported over a bed or :the like, the

upper and lower portionsof said inclosure having independentcommunication with the exterior of suchapartment. 2.
